Well, it appeared to have been a wig, because on Sunday, Hayek walked the red carpet at the 2018 BAFTAs sporting over-the-shoulder, dark brown tresses—the same length and color she has regularly showcased and did so just a day before the pre-award show bash.

The actress attended the award show with her husband, François-Henri Pinault, and wore a black gown with pink floral accents. She and fellow film stars wore black to the BAFTAs to show support for the Time’s Up campaign to stop sexual harassment and inequality in the workplace.
